Power storage module

Abstract

A power storage module includes a holder that houses a plurality of power storage devices, each including an exhaust valve, and includes an end face exposing the exhaust valves of the plurality of power storage devices; and a duct cover that covers the end face of the holder and the exhaust valves and forms an exhaust space with the end face. The duct cover includes at least one ridge protruding toward the end face of the holder and extending in a first direction parallel to the end face. The end face includes a groove or a notch that partly faces the at least one ridge and extends in a second direction intersecting the first direction.

1 . A power storage module comprising:
 a holder housing a plurality of power storage devices that include exhaust valves, the holder including an end face exposing the exhaust valves of the plurality of power storage; and   a duct cover covering an end face of the holder and exhaust valves and defining a gas flow passage with the end face, wherein   the duct cover includes at least one ridge protruding toward an end face of the holder and extending in a first direction parallel to the end face, and   the end face includes one of a groove and a notch that partly faces the at least one ridge and extends in a second direction intersecting the first direction.   
     
     
         2 . The power storage module according to  claim 1 , wherein
 the at least one ridge comprises a plurality of ridges;   a face of the duct cover that is opposite a face facing the end face has a plurality of recesses where the plurality of ridges are located, and   the duct cover is corrugated, with the plurality of ridges.   
     
     
         3 . The power storage module according to  claim 1 , wherein
 the holder includes along a periphery of the holder a peripheral wall projecting from the end face, and   the peripheral wall includes a recess allowing the at least one ridge to engage in and be housed.   
     
     
         4 . The power storage module according to  claim 1 , wherein
 the holder includes a plurality of housing parts where the plurality of power storage devices are housed and includes in the plural end faces a plurality of through holes allowing communication between an outside of the holder and insides of the plurality of housing parts, with exhaust valves of the plurality of power storage devices being exposed through a corresponding one of the plurality of through holes, the plurality of through holes being disposed at predetermined intervals, and   a leading end of the at least one ridge in the first direction at least partly overlaps with a remaining part of the end face where the plurality of through holes are absent.
